In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: Where was the Hudson's Bay Company headquartered when it controlled the Vancouver Island area? Passage:The Colony of Vancouver Island had been created in 1849 to bolster British claims to the whole island and the adjacent Gulf Islands, and to provide a North Pacific home port for the Royal Navy at Esquimalt. By the mid-1850s, the Island Colony's non-indigenous population was around 800 people; a mix of mostly British, French-Canadian, Metis, Hawaiians, but with handfuls of Iroquoians and Cree in the employ of the fur company, and a few Belgian and French Oblate priests (thousands of First Nations died due to the smallpox epidemic). Three years earlier, the Treaty of Washington had established the boundary between British North America and the United States of America west of the Rocky Mountains along the 49th parallel. The mainland area of present-day British Columbia, Canada was an unorganised territory under British sovereignty until 1858. The region was under the de facto administration of the Hudson's Bay Company, and its regional chief executive, James Douglas, who also happened to be Governor of Vancouver Island. The region was informally given the name New Caledonia, after the fur-trading district which covered the central and northern interior of the mainland west of the Rockies.

Example Input: Question: How many sales did Sean Paul's third album make? Passage:"(When You Gonna) Give It Up to Me" (known as "Give It Up to Me" in its solo version) is a reggae–dancehall song written by Sean Paul for his third album The Trinity (2005). The single meant to be released after "Temperature" was "Breakout", but was switched to "Give It Up To Me" to promote the film Step Up (2006). It is the fourth U.S. single taken from the album and the fifth UK single. It was a split single with "Never Gonna Be the Same", which was released outside the North America in June 2006 but it was finally released worldwide in October 2006. The version released as a single (the one called "(When You Gonna) Give It Up to Me", in order to differ from the album version) was a collaboration with Keyshia Cole and the song was a single from the Step Up film soundtrack. Despite The Trinity being re-released just before the single release, the version with Keyshia Cole did not make the album, despite a "radio version" being added.
